AI Technical Summary
When installing existing transformer substation accessories, construction workers directly hang safety belts on the transformer body, which cannot ensure the structural strength of the hanging point, resulting in an inability to effectively prevent the risk of falling.
A protective bracket for the insulating rod of a transformer substation was designed, including a bracket body, clamps, insulating rods, connecting rods, pulleys, safety ropes, and ratchet winches. The brackets are used to clamp the brackets to the edge of the transformer, and the safety rope passes through the fixed ring to form an operating mode with good traction effect, ensuring the stability of the safety rope.
This ensures the safety of construction personnel during the installation of transformer substation accessories. The "high-hanging, low-use" operation mode effectively prevents the risk of falls and meets safety operation standards.
